Patent CA-2091365-C (CA)
Title: Composite polymeric articles
Inventor: STEVENS HENRY GUY
IPC: B32B7/02
Filed: 1991-07-24
Granted: 2003-05-13
Abstract: Composite polymeric articles, which may be in layer or film form, comprise a larger portion of a polymer which is water-soluble at 20 ° C against a smaller proportion of a polymer which is substantially water-insoluble at that temperature. For exam-ple, a layer product may have a thin layer (e.g. less than 5µm) of insoluble polymer superimposed on a thicker layer (e.g. at least 20µm) of soluble polymer. Both polymers are conveniently polyvinyl alcohol, which is non-toxic and useful in a number of dom-estic applications e.g. as a nappy backing sheet. The insoluble portion gives water resistance but negligible mechanical strength; the soluble part gives the mechanical strength. On dissolution of the soluble portion, the insoluble portion disintegrates mechani-cally. Articles may be made by co-extrusion or by moulding.

Patent CA-2100280-C (CA)
Inventor: TRAVERS RICHARD H
IPC: F25D1/00
Filed: 1993-07-12
Granted: 1998-02-03
Abstract: The invention pertains to an auxiliary outside air refrigeration system for use in combination with a conventional refrigeration system to supply refrigeration to an enclosure whereby cold outside air is used as the cooling medium. A differential thermostatic controller monitors the temperature inside the enclosure and in theoutside atmosphere and, if the temperature inside the enclosure indicates the need for refrigeration, activates the fans of the auxiliary outside air system whenever the temperature differential between inside and outside indicates adequate potential for refrigeration. The conventional refrigeration system is energized only when the more energy-efficient outside air refrigeration system is not able to maintain adequate refrigeration within the enclosure. The controller can be used for an auxiliary outside air refrigeration system using direct exchange of air between the enclosure and the outside atmosphere or one using an air-to air heat exchanger.

Granted: 1996-08-06
Abstract: This invention is a single-lumen balloon catheter having a valve seat on the distal end of the catheter, distal of the balloon, which may be operated by a control wire having a valve plug disposed on the wire. The valve seat may be engaged by the valve plug from either direction, depending on the installation of the control wire.  In either event, if the valve plug is installed distally of the valve seat in the catheter lumen, the valve is closed by pulling on the control wire (or moving the control wire in a proximal direction) and introducing fluid through the catheter lumen through the balloon.  Alternatively, the guidewire, with its integral valve plug, may be introduced from the proximal end of the catheter and may traverse the body of the balloon to engage the valve seat in the distal end of the catheter. Pushing on the control wire will seat the valve, allowing the introduction of fluid through the catheter lumen to inflate the balloon.  The latter arrangement allows the control wire to be interchanged with other guidewires a physician may wish to use.  The balloon provided for in this invention is of a single length and does not change its axial length as it is inflated.

Abstract: An apparatus for dehydrating particulate material.      The apparatus comprises a channel having an inlet end for receiving particulate material to be dehydrated and an outlet end for discharging the particulate material in a dehydrated condition. A screw conveyor rotatably mounted in the channel advances the particulate material while stirring the particulate material to enhance the release of water and noxious vapours. A fan creates an air current in the channel to entrain water and noxious vapours released by the particulate material. The vapours are directed toward a heating chamber which incinerates dangerous and odoriferous compounds as much as possible.      The resulting gaseous media is directed through a passage in a heat-exchange relationship with the channel to elevate the temperature of the particulate material that is being processed and cause same to release water and noxious vapours. The passage is isolated from the channel to avoid direct contact between the burned gases that are released in the atmosphere with yet unburned gases aspirated from the channel.

Abstract: In a breakaway trailer brake activating mechanism mounted on a trailer surge brake actuator, one end of a tension coil spring is attached to the breakaway activating mechanism while the other end of the spring is connected to an intermediate link on a breakaway chain. The connection is such that a surplus, predetermined number of breakaway chain links, forming a slack section of the breakaway chain, are connected between the ends of the spring. The spring prevents the slack section of the breakaway chain connected between the ends of the spring from being pulled tight so as to allow for tow vehicle turns even if a safety chain is incorrectly secured. Thus, during a sharp turn of the tow vehicle, the spring will allow the reserve links of the slack section of chain to extend but not so far as to cause the trailer brake to be activated. Should the trailer become separated from the towing vehicle during towing, however, the force exerted on the breakaway chain extends the spring to the point that the slack section of the breakaway chain is pulled tight thereby causing application of the trailer surge brakes by the breakaway brake activating mechanism.

Abstract: Method for mixing granulates, powders and liquids in a continuous process, whereby the material is placed in a mixing housing and is mixed therein with the aid of a rotor equipped with mixing arms. The material is thereby moved to and fro many times during one rotation of the rotor, towards the rotor axis and away from it. For that purpose the device with which the method is implemented has longitudinal stators, mounted principally in the axial direction of the rotor, between which the mixing arms move when in operation. The mixing housing consists preferably of two chambers situated behind one another seen in the direction of the axis of the rotor and separated from one another by the rotor disk. The material which is to be mixed enters the housing in the first chamber, where it is undergoes a preliminary mix, then flows into the second chamber and is mixed further there.

Title: Non-integer sample delay active noise canceller
Inventor: LO ALLEN K
IPC: H03H21/00
Filed: 1994-04-25
Granted: 1998-03-31
Abstract: An active adaptive noise canceller (100) that inserts delays into the weight update logic of an adaptive filter to keep the filter stable.  The noise and residual noise are sensed (102, 108) and the respective sensor signals are digitized at a given sample rate for processing in the adaptive filter (113).  To eliminate the need for high sample rates while maintaining flexibility in the frequency regions over which the adaptive filter is stable, the delay (116) introduced into the weight update logic is a non-integer multiple of the sample period.  The non-integer sample delay (118) is obtained by a sample interpolation and decimation procedure.
